-n carrying outl the present invention, it is my, purpose 'toprov1de`a system of t e class described wherein yby means of a generator `adapte to be driven` from an 'eX- plosive. engine, 'a storage battery' or'y accuand, when'the latter has been exhausted, Afrom the generator, the switches bem'g `capable of manipulation so that the'lanpy feeders may be placed in circit'witli either the battery or the generator, andthe generator converted into a motor and driven from the batteryso that the driving motor or engine of the generator may be started or placed under'` its initial compression so that the ,saine ma pick up its own cycle of operation.

.It isna so my purpose toprovide an automatic switch or circuit breaker which will bel vautomatic in action andf 1located in the lchargin circuit and by means of which the 'proper ow of current to the circuit from the source of energy will .be at all times assured, the circuit breaker or switch being constructed in such manner as vto be readily tand conveniently installed in a charging cir cuit and operating to automatically break the circuit in the eventl that the current throughthe charging circuit is reversed -incident to overcharging ofl the battery and the like` Furthermore, I aim to provide a system ofthe type set forth which will embrace the desired,'features oi' simplicity,eiiiciency, durability and convenience and which may be installed and maintained at a minimum cost and readily and conveniently manipulated.y With the above and other objects 1n view, the invention consists in the construction, combination and arrangement of partshere- 5;.Thc automatic circuit inafter set forth in and falling within the sco e of the claim.

n the accompanying drawings: Figure 1 is a diagrammatic view of a battery chargmg system constructed in accordance withl tho'prescnt inventiom, Fig. Q is a vicw.n` side elevation of the automatic circuit breaker or charging switch. Fig. 3 is a sectional view therethrough.

' Referring now to the accompanying drawings in detail, the numeral 1 designates a dynamo electric machine or generator of any suitable construction and' adapted@ to be p drivenA from an internal combustion engine indicated conventionallg at 2. Some suit-l able 'form of clutch mec anism is preferably *employed between the generator and the` engine so that the generator ma be coupled up Withl and uncoupled from t e engine.

The numeral1 3 designates an automatic' circuit breaker for charging switch connectalead Wire 4 leading from one side of the generator and tcrminatin in a binding post V iran-ker 3 is, 1n the present instance, inthe form of a polarized relay composed of electromagnets G, Gwound in relatively opposite directions so that when the current is flowinvr in one direction, the magnet to the right o Fig. 2 will have a south pole, while the magnet to the left will have a north polo, while when the direction of the flow of the current changes, th'e polaritynf thc magnets will be reversed. T e'numeral designates a magnetized armatureof substantially U-Shape and hvingthe extremities of the limbs thereof forming permanent north and south poles.

The upwardly extending limbs of theI U- ed in circuit with the dynamo 1 by means of and through these openings is passed a bar 7 secured to the armature through the medium of a fastening screw 7" passed through an aperture in the interconnecting member ot the U-shapedarmature and threadedly engaging thebar 'l' so that the armature may be elevated and lowered with respect to the poles of the magnets. One end of the bar o'rlever` 7 is'fulcrumed u on a stud 8, while the opposite end the-reo carries a contact 9 ad pted to engage the contact 10 connecte to the free terminal of the windings .otv the magnets, theA other terminal ofl the terminating in one eid contact 16 of the switch 14 at the side, of such switch with the contact 13, that is to say, at the left of the switch blade. Leading from the center pivot contact of the switch 14 is a conductor 17 terminating in one pivot contact of a doublc pole double throw charging switch 1 8, while from one end pivot contact of the switch 14 leads a conductor 19 terminall connected to the remaining pivot contact o the switch .18 and to one side of the switch 18 are connected conductors 20 2O connected to'thelopposite sidesef a storage battery or accumulator 21, while the opposite side of the double pole double throw switch 18 is in the form of jacks or sockets 22 whereby another secondary or storage battery may be charged subsequent to the charging of the accumulator 21. p

`When it is desired to charge the storage battery 21, the blades of the switch 14 are thrown to the left and so yestablish electrical communication between the conductors 12 and 17 and 15 and 19, while the double lpole double throw switch 18 is thrown to the right so as to place the conductors 17 and 19 in electrical communication with the con- (luci/OTS 20, 20. met: be' in o eration, the lever 8 is swung in an upwar direction manually thereby closing the circuit at the contact 11. Current now flows from the generator through the lead wire 4, windings of the magnets 6, 6, contact 11, the respective portion of the lever 8, the conductor 12, conductors 17 and 20, through .the accumulator, the storage battery 21 and thence back to the opposite side of the generator by way of the conductors 20, 19 and 15. As long as Athe current from the generator flows in the roer direction, the polarized relay will hol lthe circuit closed at the contact 10', while when the directionof currentis reversed, the oles Vof the magnets 6, 6 will be reversed 'andP so present like poles to the poles of the armature 6 thereby releasing the lever or bar 7 and permitting the latter to gravitate to its lowered position so as to break the circuit.

Connected in multiple with the generator or dynamo is a pair of conductors 23 terminatin in one side of the double ole double girow switch 24, while multiples to the storage battery or accumulator y21 is a pair of conductors 25 terminatin "in the opposite side of the switch 24, t e ivot studs of the blades of the switch 24 eing connected by way of conductors 26 with a the generator to incassa voltmeter 2?. Thus, by means of the switch 24 the voltmcter may be electrically conv nectcd with the generator or the storage battery, according to the manipulation of the blades of the switch thereby enabling the voltage of the enerator and accumulator to be determine An ammeter 28 is preferably connected in series'with the conductor 19.

From two of the contacts at the righthand side of theA blades of the triple pole switch lead electric li ht feeders 29, which, when the blades of t is triple pole switch are thrown tothe right are in electrical communication with the storage battery 21 by. way of the conductors 20, 20, the switch 18, the conductors 17 19 and the blades of the triple pole switch. Thus, the lamps connected in the feeders ma be supplied-with energy from the accumu ator 21. lin order that the lamps connected in circuit with the feeders 29 may be supplied with energy during the charging of the accumulator 21 and receive such energy from the generator 1, l tap onto the accumulator a conductor 30 having the free terminal thereof fastened to the remaining contact 31 at the left-hand side of the tr1plc pole double throw switch 14, while the top plvot contact of the switch blades and the center contact at the right of the blades" are bridged bymeans of a section of wire 31, the lower contact to the right of the blades of the switch 14and the lowerv ivot contact of the blades being bridgef by `means of a link 32. rlhus, it will be seen that when the blades of the triple pole double throw switch 14. are thrown to the left, the generator -1 will be placed in electrical communication with the accumulator 21 so as to charge the latter, as previously described, while should one or more of the lights connected with the feed ers 29 be turned on, current will flow from one side of the generator into the particular side of the acdumulator, thence throur h theconductor 30, respective blade of t e switch 14, wire 31', the respective feeder 29 and thence back to the othery side of the generator by way of the remaimng feeder 29, the link 32, the respective blade of the switch 14, and the conductor 15.

In some instances, it may be desired to run the generator as a motor so that the internal vcombustion engine driving the generator may be placed under initial compresl connection with the accompanying drawico ings, the construction, mode of operation and manner of employing my invention will b e readily apparent.

It will, be seen that I have provided a storage battery charging system by means of which the lamps in a lighting circuit may be illuminated and whereby the engine may be placed under initial compression. By means of the contacts 22, 22 of the double pole double throw switch 18, an accumulator, other than that indicated at 21, may be charged, as will be 'readily understood by those skilled in the art to which the invention appertains. It will be observed that the automatic circuit breaker 3 acts as a safety device so that in the event of a re-` versal in the current flow, the connections between the generator and storage battery will be broken or disrupted.`

While I have herein shown and described one preferred form of my invention by way of illustration, I desire to have it understood that I do 'not limit or confine my.- self to the recise ldetails of -construction herein descri ed and delineated, as modification and variation may be made within the scope cf the claim without departing from the spirit of the invention.

I claim:

In a system of the class described, an electric generator, a storage battery, electric light feeders and a three ole double switch having certain of its po es interconnected independently of the blades, whereby in one position the `light feeders and generator will be connected to said battery and when in its other position, the generatorl will be cutout'.

In testimony whereof I afliX my signature in presence of two witnesses.
